min < value < max) - IsEmail - checks if a fields value is a valid email
- IsNumber - checks if a felds value is a number
- IsPositiveInteger - checks if fields value is an integer and greater than zero (
value > 0) - Length - checks if a fields value is a given length (min, max or both)

You can easily create your own validations, just implement the de.psdev.formvalidations.validations.Validation interface.
EditTextErrorHandler- displays the validation error on theEditTextusing thesetErrormethod
You can easily create your own error handlers, just implement the de.psdev.formvalidations.FormErrorHandler interface.
Create validation form and add some validations
final Form mForm = Form.create(); mForm.addField(Field.using(mNameEditText).validate(NotEmpty.build())); mForm.addField(Field.using(mEmailEditText).validate(NotEmpty.build()).validate(IsEmail.build())); mForm.addField(Field.using(mAgeEditText).validate(InRange.build(0, 120))); mForm.errorHandler(new EditTextErrorHandler());
Check if the form is valid
private void submit() { if (mForm.isValid()) { Toast.makeText(this, "Form is valid", Toast.LENGTH_SHORT).show(); } }
